Additional features

Multiple Appearance Directory Number

Multiple Appearance Directory Number (MADN), also known as Bridge
Line Appearance, and using Single Call Appearance (SCA) allows
multiple phones to appear as a single line to the caller. Any of the IP
Phones with the MADN feature active can initiate or answer a call, but
only one call can be active at a time. However, other clients that are part
of the same MADN line can join the active call by going off hook.
The MADN feature allows a user to prevent others from joining the call by
making the call private. In order to make the call private a special code
(Vertical Service Code) must be dialed so that the call server knows that
the call is private. In order to dial a Vertical Service Code on an
IP Phone 1120E the user must first initiate a new call by pressing the
Action Context-sensitive soft key and select
then dial the Vertical Service Code which is provided by your system
administrator or service provider.
Note: The MADN feature is only available when you connect to a call
server that supports the MADN feature. Your system administrator
manages the MADN feature and enables the MADN feature on your
IP Phone 1120E if required.
When multiple phones are configured with a MADN SCA feature, they
share one single Directory Number (DN) that is available to the user. An
incoming call to this DN or to any SIP address of the users of the MADN
SCA group, causes all the phones to ring. Also, a call initiated from any
phone of the MADN SCA group can be joined by other users within the
group.
Any user that joins a call with the MADN SCA feature can put the call on
hold and prevent other users within the MADN SCA group from joining.
